The source for VMEM is in this GitHub repository.
The following libraries are part of VMEM:
The libvmem library turns a pool of persistent memory into a volatile memory pool, similar to the system heap but kept separate and with its own malloc-style API.
See the libvmem page for documentation and examples.
NOTE: Since persistent memory support has been integrated into libmemkind, that library is the recommended choice for any new volatile usages, since it combines support for multiple types of volatile memory into a single, convenient API.
The libvmmalloc library transparently converts all the dynamic memory allocations into persistent memory allocations. This allows the use of persistent memory as volatile memory without modifying the target application.
See the libvmmalloc page for documentation and examples.
VMEM was a part of PMDK repository. It was moved out after PMDK 1.7.
